So, after you've read it all, do you have any thoughts?

I think it's terrible that they didn't rush into the B.O. again, but hey, this Detective boy mystery seems to be different. It's not about murder this time either. I think this is an illusion trick that is made to fool the eyes. Notice how Conan said something off about the stairs? Perhaps the room goes quite a bit further down than expected? Or maybe there is a trick of the eyes through the window?
